I've found no free software able to open it other than displaying:
"To view the full contents of this document, you need a later version of the PDF viewer. You can upgrade to the latest version of Adobe Reader from www.adobe.com/products/acrobat/readstep2.html For further support, go to www.adobe.com/support/products/acrreader.html"
I have never seen something like this. This reminds me at the dark ages of web browsers where web pages checked the browser string and refused to show the page if you used the wrong browser. It looks like the PDF does something similar but I'm not sure if such an anti-feature really exists for PDF files.
